鲜纹夜蛾是东南亚的一个主要公共卫生问题。各种报道表明，这种寄生虫可能代表了一个物种复合体，该地区的遗传结构可能是由地理因素和不同种类的中间宿主决定的。我们用4个微卫星座位对O进行了分析。活体成虫，起源于泰国和老挝的六种鲤科鱼类。两个不同之处。观察到活体病毒的种群。在泰国班菲，只出现了一个亚群，由两个不同的鱼类物种主持。这两个亚群都出现在老挝人民民主共和国隆州的鱼类中，但在那里的鱼类宿主中表现出非常不同的程度。我们的数据表明，尽管地理分离在影响遗传结构方面比鱼类宿主的专一性更重要，但在老挝人民民主共和国万象附近可能存在两种几乎没有杂交的刺属植物。
Opisthorchis viverriniis a major public health concern in Southeast Asia. Various reports have suggested that this parasite may represent a species complex, with genetic structure in the region perhaps being dictated by geographical factors and different species of intermediate hosts. We used four microsatellite loci to analyzeO. viverriniadult worms originating from six species of cyprinid fish in Thailand and Lao PDR. Two distinctO. viverrinipopulations were observed. In Ban Phai, Thailand, only one subgroup occurred, hosted by two different fish species. Both subgroups occurred in fish from That Luang, Lao PDR, but were represented to very different degrees among the fish hosts there. Our data suggest that, although geographical separation is more important than fish host specificity in influencing genetic structure, it is possible that two species ofOpisthorchis, with little interbreeding, are present near Vientiane in Lao PDR.
